Unless you're paying zero attention to sustainable seafood, you're aware of the plight of bluefin tuna. These apex predators are being fished to the brink of extinction. Ocean has teamed up with Entourage and Alter Eco star Adrian Grenier to get the word out to more seafood lovers that bluefin needs to come off the menu. With a beautifully shot video, Grenier sends a message about the overfishing and pollution threatening these important creatures. Check it out after the jump.

Oceana notes that bluefin can grow as large as 15 feet long and 1,500 pounds heavy. They're the ocean's fastest predators, swimming up to 50 miles per hour. Yet, the popularity of their meat has caused serious overfishing -- their populations have plummeted by over 82%.

"I couldn't sit back idly while this amazing predator is being pushed to the brink of extinction," Grenier said. "We are fishing bluefin at alarming rates, and now their spawning grounds are also threatened by the oil spill in the Gulf. We need to take action and keep the bluefin from going fast."
